“Solar does continue to surprise us,” said Gregory Nemet, who wrote How Solar Energy Became Cheap, in an email. “It seems like it shouldn’t at this point. It’s been roughly 30 percent growth each year for 30 years. And costs continue to fall so new users — and new uses — continue to emerge.”
In the past year, solar power has experienced Brobdingnagian growth, even by solar standards. According to a new report from Ember, an energy think tank, the world is on track to install 29 percent more solar energy capacity this year — a total of 593 gigawatts — compared to last year, which was already a record year. This is more than one-quarter of the electricity produced by every operating coal plant in the world combined. In 2020, the whole world had installed just 760 GW of solar in total.
